    rebuild engine

    by woodsman » Fri Feb 23, 2007 9:33 am

    After 4 hard years of riding jumping and generally abusing my poor 2003 xr100r what all needs replacement? Clutch plates? camshaft? valves? what all wears out and how can I tell if these things are worn out? All suggestions welcome!


    Thanks ahead of time! :P

    You need to do a compression test and compare that to what a shop manual says it should be. A leak down test on top of that will tell you everything you need to know about the health of your engine.
    A good shop will do both of these things to a simple engine like the XR pretty reasonably if you don't want to tackle it yourself, otherwise get a Clymer manual and go at it.
    The clutch either works or it doesnt,if it's not slipping don't sweat it. Regardless , that shop manual will tell you all about how to inspect it also. Doug

    i got a little neighbor who rides the hell of his xr100 i think its an 02 and the only thing that was worn out on it was the clutch plates and his forks felt a little soft compared to another xr 100 that had not been torchured, so a quick fork oil chang and it was back as good as new, and for the engine i have stayed on him for the last 5 years about changing the oil and cleaning the filter so nothing is really worn in there. but just curiously why do u ask if something needs to be replaced? is it hard to start? does it smoke? clutch not engage/disengage properly?

    problems

    No noticeable problems but the clutch feels a little worn. And the plastic fender on back was broken when I tried a backflip(no joke) And I am looking for an exuse to spend money on it :twisted:

    If it's not broke, don't fix it. That thing will chug along forever with not much love.

    If you need to spend some money upgrade it to CRF150R!

    not quite, I landed fine with the front a little in the air but the gave it to much gas and went backwards again.
    (Maybe I was subconsciously trying to copy Travis's double) :lol: Anyway, the back fender ate the ground and snapped under the seat and obviously I got thrown :evil: .
